verification-workflow

verification-workflow is a skill for Claude Code, Codex from JeonJe/claude-plugins. It costs 91 tokens per session (2,307 once invoked), scanned A, original, MIT.

A verification process that takes software work from requirements through research, planning, implementation, testing, review, and the final commit check. TDD means writing tests before code, but this workflow does not require that approach for every task.

In plain words
What is it for?
Use it to choose review steps based on task complexity, document research and plans, test edge cases, run linting and type checks, review code, and perform end-to-end checks when needed.
Why use it?
It reduces missed requirements, unsafe changes, weak tests, and commits that have not been independently checked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verification-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verification Workflow

A risk-gated pipeline from requirement to commit. The review/verification stages can be implemented by any agent roster — role names below (researcher, architect, reviewer, executor) are roles, not specific agents. Simple one-off work needs only self-verification (lint/type/test) plus the commit gate.

Research 단계 (복잡 작업 필수)

트리거: 3개+ 파일 변경 예상, 또는 기존 아키텍처 이해가 필요한 작업

  1. 대상 코드를 깊이 분석 (관련 클래스, 의존성, 호출 흐름)
  2. 분석 결과를 docs/{key}/research.md 등 프로젝트 문서 위치에 기록: 현재 구조 요약 / 데이터 흐름 / 제약 조건 / 변경 영향 범위
  3. 사용자에게 research.md 검토 요청 → 잘못된 이해를 사전 차단
  4. 사용자 승인 후에만 계획 단계로 진행

핵심: 잘못된 리서치는 이후 모든 단계를 망친다. 가장 비용이 큰 실패를 여기서 차단. 스킵 조건: 단순 버그 수정, 1-2파일 변경, 사용자가 "skip research" 명시

계획 출력 템플릿 (필수 준수)

## 1. 변경 파일 목록      — path + 변경 이유 한줄
## 2. 참조한 기존 구현    — path + 이 패턴을 따르는 이유
## 3. 핵심 코드 스니펫    — 주요 시그니처/핵심 로직 스케치
## 4. 대안 및 트레이드오프 — 선택 vs 대안 (최소 1개), 각각 장단점 (기록 구조: references/design-decisions.md)
## 5. 리스크             — 회귀 가능성, 성능 영향, 마이그레이션 여부
## 6. 예상 소요과 컷라인  — Phase별 구현/테스트 예상 + 근거(참조 구현 크기·파일 수·미지수),
##                        시간 초과 시 자를 순서 (동작 우선 → 기본 기능 → 심화)

참조 구현 패턴: 계획 작성 전 기존 코드에서 유사 구현을 먼저 검색한다 — 동일 도메인 유사 기능 → 동일 패턴의 다른 모듈 → 기존 설계 문서. 기존 패턴과 다르게 구현하면 반드시 이유를 트레이드오프 섹션에 기록.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
